            Null pointer check via "myPtr > 0"
            Asked 2022-Mar-30 at 01:04

            In some legacy code I came across the following null pointer check.



            Answered 2022-Mar-28 at 12:46

            Ordered comparison between a pointer and an integer is ill-formed in C++ (even when the integer is a null pointer constant such as it is in this case). The risk is that compilers are allowed to, and do, refuse to compile such code.

            You can rewrite it as either of these:



            ESlint - Error: Must use import to load ES Module
            Asked 2022-Mar-17 at 12:13

            I am currently setting up a boilerplate with React, Typescript, styled components, webpack etc. and I am getting an error when trying to run eslint:

            Error: Must use import to load ES Module

            Answered 2022-Mar-15 at 16:08

            I think the problem is that you are trying to use the deprecated babel-eslint parser, last updated a year ago, which looks like it doesn't support ES6 modules. Updating to the latest parser seems to work, at least for simple linting.

            So, do this:

            • In package.json, update the line "babel-eslint": "^10.0.2", to "@babel/eslint-parser": "^7.5.4",. This works with the code above but it may be better to use the latest version, which at the time of writing is 7.16.3.
            • Run npm i from a terminal/command prompt in the folder
            • In .eslintrc, update the parser line "parser": "babel-eslint", to "parser": "@babel/eslint-parser",
            • In .eslintrc, add "requireConfigFile": false, to the parserOptions section (underneath "ecmaVersion": 8,) (I needed this or babel was looking for config files I don't have)
            • Run the command to lint a file

            Then, for me with just your two configuration files, the error goes away and I get appropriate linting errors.

            I recently did a global install of create-react-app and am having an issue where sometimes, when I'm working on a project, instead of editing directly what I have rendered in , it creates this container around the entire app.

            So after MUCH research and testing, I finally figured this out and I hope it can save anyone in the same situation I was in 😊

            I have found two solutions that can solve this, one with a .env file that sometimes works, and the other solution is with css that I want to say always will solve this issue.

            Fix #1: .env solution

            In the root folder level (the same level as the .gitignore, package.json,, yarn.lock, /src), create a .env file and include the following in it:



            VS 2022 - Convert to file-scoped namespace in all files
            Asked 2022-Mar-09 at 08:44

            I'm converting my project to .NET 6 and I want to use filescoped namespaces everywhere. But the conversion tool exists only in the editor.

            Has anyone found out if there's a way to run this editor function across all files in solution at once? (Looks like Rider has that function)



            Answered 2022-Mar-09 at 08:44

            Adding a rule to use file scoped namespaces in .editorconfig worked for me:

            • create an .editorconfig file in the solution directory
            • add following line/content below (docs, code - IDE0161)

            Transparent iFrame blocks mouse event when using react-scripts start
            Asked 2022-Mar-04 at 16:41

            Has anyone ever come across this issue?

            When using react-scripts start, everything seems ok on first load. As soon as a change is made to a file, all the mouse event seem to stop working (can't click on buttons, inputs, no tooltips etc.), even though the browser appears to update.

            If I refresh the page the events work again, until a file is changed.

            This isn't a problem in production as the watcher isn't involved there.

            Any ideas?

            I've found the problem but I'm not sure what the solution is. It appears that a iFrame is added to the DOM when the watcher reloads. It looks like it has something to do with licenses. The body within the iFrame is empty but there is some minified JS with a comment on the top line:

            /*! For license information please see iframe-bundle.js.LICENSE.txt */

            Does anyone know how to prevent this iFrame appearing.

            After taking a step back, I realized that I could try out what I did to fix the sass-loader issue: downgrading major versions.


            • Downgraded style-loader 1 major version to 2.0.0: npm i style-loader@2.0.0
            • Then, as luck would have it, I ran into the same issue with css-loader
            • Downgraded css-loader 1 major version to 5.2.7: npm i css-loader@5.2.7


            By downgrading all of the loaders one major version, I was able to get it to work.



            Is it safe to bind an unsigned int to a signed int reference?
            Asked 2022-Feb-09 at 07:17

            After coming across something similar in a co-worker's code, I'm having trouble understanding why/how this code executes without compiler warnings or errors.



            Answered 2022-Feb-09 at 07:17

            References can't bind to objects with different type directly. Given const int& s = u;, u is implicitly converted to int firstly, which is a temporary, a brand-new object and then s binds to the temporary int. (Lvalue-references to const (and rvalue-references) could bind to temporaries.) The lifetime of the temporary is prolonged to the lifetime of s, i.e. it'll be destroyed when get out of main.



            Why set the stop flag using `memory_order_seq_cst`, if you check it with `memory_order_relaxed`?
            Asked 2022-Jan-05 at 15:38

            Herb Sutter, in his "atomic<> weapons" talk, shows several example uses of atomics, and one of them boils down to following: (video link, timestamped)

            • A main thread launches several worker threads.

            • Workers check the stop flag:



            Answered 2022-Jan-05 at 14:48
            mo_relaxed is fine for both load and store of a stop flag

            There's also no meaningful latency benefit to stronger memory orders, even if latency of seeing a change to a keep_running or exit_now flag was important.

            IDK why Herb thinks shouldn't be relaxed; in his talk, his slides have a comment that says // not relaxed on the assignment, but he doesn't say anything about the store side before moving on to "is it worth it".

            Of course, the load runs inside the worker loop, but the store runs only once, and Herb really likes to recommend sticking with SC unless you have a performance reason that truly justifies using something else. I hope that wasn't his only reason; I find that unhelpful when trying to understand what memory order would actually be necessary and why. But anyway, I think either that or a mistake on his part.

            The ISO C++ standard doesn't say anything about how soon stores become visible or what might influence that, just Section Forward progress

            18. An implementation should ensure that the last value (in modification order) assigned by an atomic or synchronization operation will become visible to all other threads in a finite period of time.

            Another thread can loop arbitrarily many times before its load actually sees this store value, even if they're both seq_cst, assuming there's no other synchronization of any kind between them. Low inter-thread latency is a performance issue, not correctness / formal guarantee.

            And non-infinite inter-thread latency is apparently only a "should" QOI (quality of implementation) issue. :P Nothing in the standard suggests that seq_cst would help on an implementation where store visibility could be delayed indefinitely, although one might guess that could be the case, e.g. on a hypothetical implementation with explicit cache flushes instead of cache coherency. (Although such an implementation is probably not practically usable in terms of performance with CPUs anything like what we have now; every release and/or acquire operation would have to flush the whole cache.)

            On real hardware (which uses some form of MESI cache coherency), different memory orders for store or load don't make stores visible sooner in real time, they just control whether later operations can become globally visible while still waiting for the store to commit from the store buffer to L1d cache. (After invalidating any other copies of the line.)

            Stronger orders, and barriers, don't make things happen sooner in an absolute sense, they just delay other things until they're allowed to happen relative to the store or load. (This is the case on all real-world CPUs AFAIK; they always try to make stores visible to other cores ASAP anyway, so the store buffer doesn't fill up, and

            See also (my similar answers on):

            The second Q&A is about x86 where commit from the store buffer to L1d cache is in program order. That limits how far past a cache-miss store execution can get, and also any possible benefit of putting a release or seq_cst fence after the store to prevent later stores (and loads) from maybe competing for resources. (x86 microarchitectures will do RFO (read for ownership) before stores reach the head of the store buffer, and plain loads normally compete for resources to track RFOs we're waiting for a response to.) But these effects are extremely minor in terms of something like exiting another thread; only very small scale reordering.

            because who cares if the thread stops with a slightly bigger delay.

            More like, who cares if the thread gets more work done by not making loads/stores after the load wait for the check to complete. (Of course, this work will get discarded if it's in the shadow of a a mis-speculated branch on the load result when we eventually load true.) The cost of rolling back to a consistent state after a branch mispredict is more or less independent of how much already-executed work had happened beyond the mispredicted branch. And it's a stop flag so the total amount of wasted work costing cache/memory bandwidth for other CPUs is pretty minimal.

            That phrasing makes it sound like an acquire load or release store would actually get the the store seen sooner in absolute real time, rather than just relative to other code in this thread. (Which is not the case).

            The benefit is more instruction-level and memory-level parallelism across loop iterations when the load produces a false. And simply avoiding running extra instructions on ISAs where an acquire or especially an SC load needs extra instructions, especially expensive 2-way barrier instructions, not like ARM64 ldapr.

            BTW, Herb is right that the dirty flag can also be relaxed, only because of the thread.join sync between the reader and any possible writer. Otherwise yeah, release / acquire.

            But in this case, dirty only needs to be atomic<> at all because of possible simultaneous writers all storing the same value, which ISO C++ still deems data-race UB. e.g. because of the theoretical possibility of hardware race-detection that traps on conflicting non-atomic accesses.



            React hooks: call component as function vs render as element
            Asked 2021-Dec-25 at 09:13

            Say we have component:



            Answered 2021-Dec-12 at 10:39

            Here are some implications of calling component as function vs rendering it as element.

            1. Potential violation of rules of hooks

            When you call a component as a function (see TestB() below) and it contains usage of hooks inside it, in that case react thinks the hooks within that function belongs to the parent component. Now if you conditionally render that component (TestB()) you will violate one of the rules of hooks. Check the example below, click the re-render button to see the error:

            Error: Rendered fewer hooks than expected. This may be caused by an accidental early return statement.



            Use recode to mutate across multiple columns using named list of named vectors
            Asked 2021-Dec-19 at 17:00

            I couldn't find a question similar to the one that I have here. I have a very large named list of named vectors that match column names in a dataframe. I would like to use the list of named vectors to replace values in the dataframe columns that match each list element's name. That is, the name of the vector in the list matches the name of the dataframe column and the key-value pair in each vector element will be used to recode the column.

            Reprex below:



            Answered 2021-Dec-13 at 04:44

            One work around would be to use your map2_dfr code, but then bind the columns that are needed to the map2_dfr output. Though you still have to drop the names column.
